These messages disappear after changes in the auth and anvil config but I ran
into the following problem:

dovecot[355234]: master: Dovecot v2.2.36.4 (baf9232c1) starting up for imap
dovecot[355234]: master: Error: service(auth): command startup failed, throttling for 2 secs

I guess the solution is simple but I can't find it :-(
